(See Bellotti, Atti Soc. It. Sci. Nat., Milan. April 20. 1877, May 30, 1891, May 22, 1802.) 



The following account of the genus Arctozenus, Gill, will occur in Jordan and Ever- 

 nianu's new manual. 



ARCTOZENUS, Gill. 



Arctozenus, Gill, l'roc. Ac. Nat. Sci. l'hila., 1864, 188. 



Head elongate, conical, the snout attenuate, the jaws straight, the lower mostly cov- 

 ered by the upper; teeth of lower jaw anteriorly slender, recurved, and distant; posteriorly 

 small, acute, and close together. This genus is closely related to Sudis, from which it differs 

 mainly in the absence of fang-like teeth. From Paralepis it differs in the position of the 

 ventral tins, which are entirely behind the dorsal. The known species belong to the deep 

 waters of Arctic America ; long, slender tishes suggesting the Barracuda in outline. («,<«-:, 

 northern; Zivos, strange.) 



«. Teeth comparatively strung; Atlantic species, A. borealis. 



aa. Teeth comparatively weak : Pacific species A. coruscans. 



A. coruscans was described by Jordan and Gilbert, in 1880 (Proc. IT. S. N. M., 411), from 

 off Port Townsend, Washington. 



Page 120: Paralepis intermedins, Poey, is referred to Sudis. 



Odontostomus atratus, Alcock (Journ. Asiatic Soc. of Bengal, lxh, Part n, No. 4, 1883, 

 p. 14, PI. ix. fig. 1), was obtained from 128 fathoms in the Bay of Bengal. 



Page 128: Polyipnus spinosus. The locality of the specimen assigned by Alcock to this 

 species was Investigator station 115, and the range of depth was 108 to 220 fathoms — not 

 210. as stated in the text. 



Tdiaeanthus antrostomus, Gilbert, was obtained by the Albatross in (503 fathoms at 

 station 29S0, off the coast of southern California (Proc. U. S. N. M., xm, 1800, 54). 



Page 120: Halosaurus parvipinnis, Alcock (Halosaurus parvipinnis, Alcock, Ann. and 

 Mag. Nat. Hist,, November, 1892, 362). 



This species, represented by a single female, about 15 inches long, with gravid ovaries, 

 taken by the Investigator at station 122, Laccadive Sea, 805 to 880 fathoms, has the scales 

 of the lateral line but little larger than those of the rest of the body, and probably belongs 

 to the restricted genus Halosaurus. 



Page 134: Aldrovandia mediorostris (Giiuther) [Challenger Beport, xxn, 239, PI. lix, 

 fig. C]. A single specimen, 17A inches long, was obtained by the Challenger at station 207, 

 west of the Philippine Islands, at a depth of 700 fathoms. 



Page 132: Aldrovandia affinis (Giinther, Ann. and Mag. Nat. Hist., 1877, 444; Chal- 

 lenger Beport, xxii, 241, PL lix, fig. b: Alcock, op. cit., October, 1800, 300) is recorded from 

 south of Japan, 505 fathoms, and the Arabian Sea, 1,000 fathoms. 



A. Hoslcynii, Alcock, loc. cit., is closely allied to, if not identical with, the preceding, 

 and was obtained from 1,000 fathoms in the Arabian Sea, A good figure is given in "■Illus- 

 trations of the Zoology of H. M. S. Investigator," Part I, PI. vn, tig. 3, Calcutta, 1S02. 



Aldrovandia anguilliformis (Holosaurus anguilliformis, Alcock, Ann. and Mag. Nat. 

 Hist., December, 1889, 453) was obtained by the Investigator in the Gulf of Manaar at a 

 depth of G75 fathoms.
